To all whom it may concern:

Be it known that I, DANIEL Hosvonn, a citizen of. the United States,residing at Cleveland, in the county of Cuyahoga and State of ()hio,have invented certain new and useful Improvements in Fluid-DistributingSystems, and dodeclare that the following 1s a full, clear, and exactdescription of the invention, which will ena le others skilled in theart to which it appertains to make and use thesame. V

My invention relates to a new system of liquid distribution, structedand adapted to operate, suhstantially as shown and described andparticularly pointed out in the claims.

In the accompanying drawings, Figure 1- is an elevation partially insection and more or less diagrammatic, as a Whole, of the gate valvemechanism and the associated valves, as hereinafter fully described.Fig, 2 is a more or less diagrammatic view of an installation or plantembodying my new -systern, as also hereinafter more fully descrilc ed..I The system or installation thus shownis designed moreespecially forthe distrihution of water under pressure, and may be employed on a'smallor on a large scale with equal adaptability to conditions.

Aconnnon use of the invention is in connectionwith water supply forvillages and towns, in which a reservoir or tank-T is adapted to receiveand hold a supply of water under such head and pressure as willinaintain'the supply in the mains Whenthe pumping station or source ofpressure ceases to do its work. Apunip orpumping station or itsequivalent is, therefore, a necessary constituentof the system. Theinvention re sides between these two points, the pump P and tank T, andcomprises what I prefer to call a long distance gate valve V, adapted tocontrol the flow of liquid to the tank directly through or from themains, and to its open or closed according as to whether there is to benormal or specially high pressure put u on the system. This arrangementof parts a so provldes for the direct discharge of the tank into themain past a check valve It in the same being conv v 7 7! s case pressureliy tne pump is diminished or v on falls 'relow the pressure due at theliqmd 1n the tank or reser for any'r to the head voir. This will appearmore clearly hereinafter, and in connection with the said hydraulicallyoperated gate valve V and check valve K. i employ the check valve G andthree-way valve N, and pipe connections in which said valves sev allyare located.

At the letters of 2 ;re'shown a relatively small pipe L, which leads tothe tank, and mains l, which, presumally, distribute the Water to thetown, and said pipes ohviously would he of widely dill'ercnt proporticns, but of course are open. one into the other, and the same proportionapplios at the right of Fig. 2 with the tvrosizes of pipe M.

New, recurring to the operation of the eye te1n, il it be desired toincrease the pressure in the main i e between the nine and the tanl; teadegree greater than the head due to the height'of the tank or reservoirwill ailord, and at the same time permit of he tanlr or reservoirfeeding into the main pipe should the pump fail to operate, 1 divide themain pipe at a point where the special high pres sure service is to stopinto two paths including hy-path or pass B, which passes around checkvalve Kin the main line, and said valve is so arranged that it willclose with any flow of the liquid toward the tank or rcservoir and openw a any flow of or away from In the,

the tank or resel voir into the mains secondary or by path l5 there isplaced the sic-called long distance hydraulically 0 eratod gatc-valveThis valve is normal y open for the flow of liquid in either direction,hutrnay be closed from any pre-arranged station having a three way valveN, and when closed the pressure main M from the pump to the valves V andK. may be raisedto the maximum, with the tank shut off. But should thepump fail, the mains will be supplied from tank or reservoir T throughcheck valve K, even though the attendant at N should fail. to open thethree way valve and thus open gate valve V.

cylinder 5 is mounted centrally above sonable' romptness when pressureuponposite sides of the pistonis equal, and t 0 opening of said-valvecan only occur with excess pressure from beneath. Such excess pressureis through pipe F from the main and y way of by-pass H, while pressureover or upon piston C ls-through suitable piping 6 to main pipe M at anydesired point, and at 'which oint a three-way valve N and a drain 7 arecoated. In the pi e connection F I place a check valve G, an the by-passH is a comparatively small pipe about this valve. This allows the liquidto flow from the tank or reservoir into cylinder J freely, but owing tocheck-valve G in the direct line 'and the relatively small pipe of theby-pass, the

liquid will flow from the cylinder to the tank or reservoir slowly, thuscushioning the action of valve piston C.

If the three-way va'lve N is at a position where the pressure'from themain pipe is shut ofi fr'om'cylinderJ and the drain 7 open,

there is no pressure on the top of the piston but exhaust from over saidpiston instead,

and owing to the pressure on the lower side of the iston through pipe Fand b%pass H,

' the va ve Vshould e wide open. 40

ut if the three-way ,valve N should now be placed in such position. thatthe ressure from'the main pipe can enter the va ve cylinder J throughpipe 6, the piston would be forced downward ue tothe excess area of theupper face of the piston and the said long distance valve'V would beclosed. j

Presumably the check valve K and gate valve V are-locatedrelatively nearto the reservoir orstank, while valve N may be at a 50 great distancetherefrom.

Among the ad antages of the foregoing I may note first that, normally,the li uid has arr-unobstructed passage-way from t e tank ern'eservoirto the service lines but that both the artificially sustained pressurefrom the pump, and the back pressure'from the tank may be open to themainat the same'time.

Secondly, that, in a system of water works for small towns and villages,it has been customary to have a. tank or reservoir at some high point,which was filled intermittently by means of a pump. Of course, the pres:

sure in the main piping could not in that case be increased higher thanthe pressure due to the height of the tank or reservoinwhich had itsoverflow, and in case of fire no additional pressure could be obtained.On the con trary, with my improved systemof valves and connections, theressure in the main distributing pipes can e raised to an excesspressure in'case of fire or the like, dependent on the capacity of thepump, and at the same time leave the tank with a full head so that itwill supply the-main piping incase the pump is shutdown and theoperator. fails to 0 en the gate valve. Such excess pressure, 0 viously,obtained by the closing of gate valve V under. pressure upon piston 0through pipe 6, with three-way-valve N open to the main, check valve Kbeing closed also. Then in case the artificially sustained pressure isweakened below tank pressure, the

pressure from the tank will assert itself andsupply the main. I can,therefore, throw pressure into the main and into the tank at the sametime by opening gate valve "V, as shown, and this is the normalworking-relation, or I can cut oil pressure to the tank by closing valveV through pipe 6.

From the foregoing description it will be' understood that the pump isfor any suitable water connections, and"that the tower or receptacle isan auxiliary to the system designed to be used more particularly whenthepump fails to opeiate. In that case the water would flow past valve Keven though valve V were closed, but such flow of water from thereservoir would open valveV through the line F if the drain valve Nshould be opened.

What I claim is 1. A system of fluid distribution comprising a pump anda reservoir and pipes operatively uniting said parts, a check valve insaid pipes adapted to be forced to its seat by back pressure from thepump, a by-pass, a gate valve positioned in said by-pass, and a fluidcontrolled piston connected with said gate valve and normally underoperativecontrol of the pressure from the reservoir to open said valve.7

2. In water distribution, a set of pipes and a reservoir open thereto,one of said pipes having a check valve and a by-pass about saidcheckvalve having a gate valve to govcm the flow of fluid to thereservoir, and means to close said gate valve comprising a cylinder, adifferential piston therein operatively connected, with said gate valveand pipes for the admission of water to opposite sides of said piston,one of said pipes havlng a three-way valve to control the flow of wateron the larger side of said differential piston, and the other pipehaving a check valve and a by-pass substantially as shown and described.
